whats this body part called please

hi, new to this forum!

Just bought my first Landrover 110 Defender, ex mod 1994.

Im after a body panel trim thingy.
Its where the lower part of the door shuts on the body.
there is a rubber seal mounted to a plate the length of the door. Im after that plate and the rubber seal for all four lower door shuts as they are rotton on the car.

If anyone knows the proper name for these please ? thanks

is it a sill panel, like this one?

I would start with two of these at a guess.
LAND ROVER DEFENDER FRONT DOOR BOTTOM SEAL (UP TO LA933876) - wapsipurtlandrover
then look at the other part numbers mentioned

^^^^ thanks guys.

I think I found it from the site you mentioned its called seal retainer. only showing the one for the rear doors but maybe same for the fronts.
DEFENDER REAR DOOR FLOOR SEAL METAL RETAINER - wapsipurtlandrover

I rang up my local landrover , was on the phone for 15mins and at they end they said it was 'probably obsolete'
